My husband says this dish is restaurant quality. It can be made ahead and kept in the refrigerator overnight. Very filling and great served with a salad and garlic bread.
You can make this dish ahead--just cover and refrigerate or freeze after you've spread the final layer of marinara sauce. Serve with a salad and breadsticks to round out the meal.
The relish that accompanies these slightly spicy cakes reminds me of the pickley olive salad you get in a New Orleans muffuletta sandwich; in fact, as a variation, I like to make salmon cake sandwiches.
